  • Process for producing fiber composite investment castings
    Patent number: 5649585
    Abstract: At least one preliminary pattern body, which is then used as part of a pattern or the pattern itself, is produced with fibers and a pattern material. A ceramic mold is formed around the pattern with a portion of the fibers having ends embedded into the mold. The pattern material is removed and finally, metal in liquid, liquid-solid or powdery form is introduced into the mold, wherein the metal is at least partially liquefied in the mold when it is introduced in powdery form. This process allows investment castings having an increased resistance to be produced with relatively simple casting equipment.
